WINDOW-BEAD FASTENER.

Specification of Letters Patent.

Patented June 29, 11915.

Application filed November 28, 1911. Serial No. 662,803.

To all whom it may concern Be it known that I, HENRY C. TRIPP, of Auburn, in the county of Cayuga, in the State of New York, have invented new and useful Improvements in Window-Bead Fasteners, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in window bead fasteners and refers more particularly to the washers or metallic inserts for receiving and forming bearings for the heads of the fastening screws by which the stops are secured to the window frame.

The primary object is to provide the metallic bearings or inserts with pointed spurs surrounding a central laterally elongated opening whereby the disks may be easily and quickly secured to the stop without liability of working loose from shrinkage of the wood or other cause, and at the same time holding said bearings against turning when the screws which are passed through the openings are finally tightened.

Another object is to provide these bearings with inwardly projecting reinforcing ribs adapted to enter the screw holes in the stop to stifien the washers and enable them to be made from comparatively thin sheet metal.

A still further object is to depress the central portions of the washer surrounding the openings for receiving the head of the screw and permitting it to lie flush with the surface of the washer when the screws are tightened.

Other objects and uses will be brought out in the following description:

In the drawings-Figure 1 is a perspective view of a portion of a window frame, sash and adjustable stop showing my improved fastening means for the stop. Fig. 2 is an enlarged horizontal sectional view through a portion of the window frame, sash and stop and my improved fastening device. Fig. 3 is an enlarged face view of a portion of a detached stop showing the metallic insert and screw therein. Figs. 4 and 5 are enlarged sectional views taken respectively on lines 44 and 55 Fig. 3. Fig. 6 is a perspective view of the detached insert or washer.

In order that my invention may be clearly understood I have shown portions of a window frame 1, sash -2- and adjustable window stop .3 for guiding the sash in its vertical movement and holding it against rattling, said sash being guided between the stop -3- and a parting strip l-.

The means for fastening the stop -3 to the frame and permitting lateral adjustment of the stop comprises one or more washers 5 and a corresponding number of screws -6, each washer being made of comparatively thin sheet metal circular in form and provided with a series ofintegral inwardly projecting pointed spurs -7- preferably arranged uniform distances apart about a central opening -8- through said washer. In this instance the spurs 7 are stamped or pressed up from the marginal edge of the washer which is also provided with inwardly projecting reinforcing ribs or flanges -9- integral with the main body at opposite sides of the opening 8. his opening is elongated in one direction or laterally so that when applied to the stop, its greatest length will extend transversely thereof as best seen in Fig. 8, the flanges 9- being located along the edges of the opening 8 and are adapted to enter a screw hole or opening -10- in the stop to form a suitable bearing for the sides of the screw. The portions of the washer -5 surrounding the opening -8 are depressed inwardly at 11- for receiving the head as -12 of the screw 6-, thus permitting the outer face of the screw to lie substantially coincident or flush with the outer face of the washer when tightened to hold the stop in place.

In placing the washer upon the stop, its opening -S- is registered with the opening -l0- so that its greatest length eX- tends transversely of or at right angles to the length of the stop, whereupon said washer may be driven inwardly to force its spurs into the wood of the stop, thereby holding the washer firmly thereon against turning or accidental displacement even though the Wood may shrink away from the edges thereof, the flanges 8- also serving to prevent turning of the washer particularly when the screw is tightened when its frictional engagement with the washer is most excessive. In most instances, however, I prefer to sink the washer into the wood of the stop and for this purpose the outer face of the stop is bored to form a shallow recess -13 of substantially the thickness of the washer so that the latter when placed in operative position will be substantially flush with the outer surface of the stop as best seen in Figs. 2, 4c and 5.

I have shown and described this particular fastening means as applied to window stops but it is evident that it is equally applicable to door stops, weather strips and similar uses and therefore I do not wish to limit myself to wind ow stops nor to the precise construction shown and described as it evident that the washer may be made in other forms than circular, the main feature of the invention consisting in providing said disk with inwardly projecting spurs surrounding a central opening which is elongated laterally in combination with theintegral ribs along the edges ofthe opening for reinforcing this portion of the disk where it is subjected to most severe strains by the tightening of the screw.

What I claim is In combination with a sash-guiding stop Copies of this patent may be obtained for five cents each, by addressing the having a screw hole of greater transverse width than the diameter of the screw which it is to receive, a circular washer applied to .the face of the stop around the screw hole and provided with a diametrical slot elongated transversely of the stop, the portions of the washer at opposite sides of but adj acent to the slot being provided with inwardly projecting flanges spaced apart a distance corresponding approximately to the diameter of the screw and disposed at substantially right angles to the body of the main washer so as to form relatively wide bearings for the screw throughout the length of the slot, and a screw passed through the slot and hole in the top.

In witness whereof I have hereunto set my hand onthis'15th day of November 1911.

HENRY C. TRIPP.
